+[![npm dm](https://img.shields.io/npm/dm/@sentry/node.svg)](https://www.npmjs.com/package/@sentry/node)

+- [TypeDoc](http://getsentry.github.io/sentry-javascript/)
+
+## Usage
+
+To use this SDK, call `init(options)` as early as possible in the main entry module. This will initialize the SDK and
+hook into the environment. Note that you can turn off almost all side effects using the respective options.
+
+```javascript
+// ES5 Syntax
+const Sentry = require('@sentry/node');
+// ES6 Syntax
+import * as Sentry from '@sentry/node';
+
+Sentry.init({
+  dsn: '__DSN__',
+  // ...
+});
+```
+
+To set context information or send manual events, use the exported functions of `@sentry/node`. Note that these
+functions will not perform any action before you have called `init()`:
+
+```javascript
+// Set user information, as well as tags and further extras
+Sentry.configureScope(scope => {
+  scope.setExtra('battery', 0.7);
+  scope.setTag('user_mode', 'admin');
+  scope.setUser({ id: '4711' });
+  // scope.clear();
+});
+
+// Add a breadcrumb for future events
+Sentry.addBreadcrumb({
+  message: 'My Breadcrumb',
+  // ...
+});
+
+// Capture exceptions, messages or manual events
+Sentry.captureMessage('Hello, world!');
+Sentry.captureException(new Error('Good bye'));
+Sentry.captureEvent({
+  message: 'Manual',
+  stacktrace: [
+    // ...
+  ],
+});
+```
